I recently bought a 150W Visi-Therm heater for my 55gal tank (had meant to get the Stealth version but oh well). This heater recommended for 40 gal tanks but sticking with the 2-3W per gallon rule, this should be fine for what I needed. The problem is that the thermostat is set at 72 but the water temp is about 77, been this way for about two days. My apartment is warm but not nearly this warm. Should I be concerned about this and consider returning it or just keep turning down the heat but monitor closely?
Thanks!
Thanks!
